Answer:

117°

Step-by-step explanation:

The angle is obtuse, so thus greater than 90°. And the angles of a triangle must always add up to 180°, so 31 + 32 = 63, then 180 - 63 = 117°

You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
